紙装置。A cassette with at least an open top front, a rotating bottom plate rotatably provided inside the cassette and on which paper is placed, and a feeder disposed above the front of the cassette. In a paper feeding device having a paper roller and a pressure means that urges the rotating bottom plate upward to press the paper against the paper feeding roller, a pad holding member is rotatable at the bottom of the rotating bottom plate. A friction pad is fixed to the front upper part of this pad holding member, a hole is formed in the part of the rotating bottom plate that faces this friction pad, and the pad holding member is biased to move the friction pad to the rotating bottom plate. A spring is provided that protrudes upward from the hole, and a detection means for detecting that there is only one sheet of paper on the rotary bottom plate and outputting an output signal is disposed, and a pad is arranged in response to the output signal of the detection means. A paper feeding device comprising a friction pad release means for rotating a holding member against the elastic force of a spring to lower the friction pad from a hole in a rotating bottom plate.
